The slogan of keeping the distance between cars is: large transport vehicles strongly warn: "What happens when an egg hits a stone?" ; The tanker is imposing: "The tiger's ass can't be touched!" Wait a minute. Safe distance refers to the necessary distance between the rear vehicle and the front vehicle in order to avoid accidental collision with the front vehicle. Keeping a safe distance is the most direct, effective, extensive and fundamental way to prevent rear-end collision.

Safe distance:

When driving at high speed, when the vehicle speed is above 100km/h, the distance between vehicles should be above 100 m. When the vehicle speed is above 60km/h, the safe distance should be equal to the vehicle speed; When the vehicle speed is 80km/h, the safe distance is 80 meters; The safe distance between vehicles with a speed of 50km/h is not less than 50m.

Influencing factors:

The distance between vehicles directly affects the safety and stability of vehicles on the track. If it is too large, it will increase the internal bias of the vehicle, reduce the effective width of the vehicle body, increase the deflection of the vehicle and correspondingly improve the design strength of the vehicle.
